JAMES M. WELCH, OF SHEPHERDSTOWN, OHIO.

ADJUSTABLE MEASURING-SCOOP.

T0 all whom t may concern:

Be it known that l, JAMES M. VVnLoI-I, a citizen of the United States of America, and resident of Shepherdstown, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Adj ustable Measuring-Scoops, o-f which the following is a specification.

This invention relates broadly to measuring scoops, and specifically to a device designed primarily for grocers use and adapted for dispensing sugar, coffee, rice or other dry groceries sold in bulk; and it has for its primary object to provide a scoop or dipper which is adapted to be readily adjusted to increase or diminish its capacity for accurately measuring materials of various kinds.

A further object is to provide a scoop which may be so accurately adjusted to fix its capacity for measuring a certain quantity of material that the necessity of the users returning from the weighing scales to the main receptacle or container for a slight additional quantity, or for putting back a slight excess quantity, is practically obviated.

Another c lect of the invention is to provide a measuring vessel having telescoping parts provided with novel means of adjust.- ment which admit of movement of said parts any desired distance with respect to each other without the danger of instantaneous transference to the limit of the telescoping movement.

It is well known that telescoping members frequently assume binding relation, and where a stud or like element carried by one member operates in a slot provided in the other in alinement with the direction of movement of said members, considerable force is oftentimes required to start movement of one member with respect to the other; and, once started, the movement is practically instantaneous, resulting in the applied force carrying said members past the desired point of adjustment, if not to the extreme limit of possible adjustment.

As before indicated, it is a purpose of the present invent-ion to obviate the recited objection of employing an adjustment in which a slot in alinement with the direction of telescoping movement is provided.

Another object of the invention is to provide a vessel composed of telescoping sec- Speccaton of Letters Patent.

tions and provided with at guideway or guide-slot which, throughout all degrees of adjustment of said sect-ions, is maintained closed against the passage of dry material therethrough without the employment of a third part or element designed for such purpose.

A still further object within the contemplation of this invention is to provide a measuring device who-se mouth is so formed,

that the material measured therein may be readily leveled without the employment of a straight-edge or other leveling tool, and also that its insertion within the mouth of a paper bag for emptying the contents may be readily accomplished.

lVith these and other objects in view, the invention inally resides in the features of construct-ion, arrangement of parts and combinations of elements which will hereinafter be exemplified, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the invention; Fig. 2 is a partial vertical section on the line 2 2, Fig. l; and Fig. 3 is a cross section on the line 3-8, Fig. l.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views-1 indicates an outer cylindrical casing having a fixed bottom 2. An inner cylindrical casing 3 is fitted snugly within the casing l and is adapted to telesco-pe with relation to the latter for changing the capacity of the vessel of which said casings form complemental parts or sections.

Provided in the outer casing l is a diagonally extending slot fl through which is directed a bolt 5 having its end projected through an aperture 6 provided therefor in the inner casing 3. Said bolt is preferably fixed in a handle 7 so that turning movement of the latter will produce a corresponding movement in the bolt. Said bolt has its end threaded, and a nut 8 is received thereon whereby, when said bolt is turned, the nut and the handle are caused to approach each other for exerting a binding pressure against the interposed sections, or to separate for releasing such pressure, according to the direction of the turning movement. A split spring washer 9 is preferably interposed between the nut and the
